Maria Corazon Aquino was born January 25, 1933, in Tarlac, Philippines. Her husband had been an opponent of Ferdinand Marcos and was assassinated upon returning from exile. When Marcos unexpectedly called for elections in 1986, Corazon Aquino became the unified opposition's presidential candidate. She took office after Marcos fled the country, and was popular at first but later opinion was mixed.
Maria Corazon Aquino (born Jan. 25, 1933, Tarlac province, Phil.—died Aug. 1, 2009, Makati) political leader (from 1983) and president (1986–92) of the Philippines who restored democratic rule in that country after the long dictatorship of Ferdinand Marcos.
Corazon Cojuangco was born into a wealthy, politically prominent family based in Tarlac province, north of Manila. She graduated from Mount St. Vincent College in New York City in 1954 but abandoned further studies in 1955 to marry Benigno Simeon Aquino, Jr., who was then a promising young politician. Corazon remained in the background during her husband's subsequent career, rearing their five children at home. Her husband, who had become a prominent opposition politician, was jailed by Marcos for eight years (1972–80), and Corazon accompanied him into exile in the United States in 1980. Benigno was assassinated upon his return to the Philippines in August 1983. This event galvanized opposition to the Marcos government.
When Ferdinand E. Marcos unexpectedly called for presidential elections in February 1986, Corazon Aquino became the unified opposition's presidential candidate. Though she was officially reported to have lost the election to Marcos, Aquino and her supporters challenged the results, charging widespread voting fraud. High officials in the Philippine military soon publicly renounced Marcos' continued rule and proclaimed Aquino the Philippines' rightful president. On Feb. 25, 1986, both Aquino and Marcos were inaugurated as president by their respective supporters, but that same day Marcos fled the country.
In March 1986 Aquino proclaimed a provisional constitution and soon thereafter appointed a commission to write a new constitution. The resulting document, which restored the bicameral Congress abolished by Marcos in 1973, was ratified by a landslide popular vote in February 1987. Aquino held elections to the new Congress and broke up the monopolies held by Marcos' allies over the economy, which experienced steady growth for several years. But she failed to undertake fundamental economic or social reforms, and her popularity steadily declined as she faced continual outcries over economic injustice and political corruption. These problems were exacerbated by persistent warfare between the communist insurgency and a military whose loyalties to Aquino were uncertain. In general, her economic policies were criticized for being mixed or faltering in the face of mass poverty. Aquino was succeeded in office by her former defense secretary, Fidel Ramos.
